摘要
本文通过恒温水浴法和溶剂热法分别合成了两种配合物Fe(3PCA)_(2)(H_(2)O)_(2)(1)和[Cu(3PCA)(Im)]_(n)(2)(3PCA=pyrazole-3-carboxylic acid,Im=imidazole),并用X-射线单晶衍射仪测定了它们的晶体结构。结果表明:配合物(1)属于单斜晶系,空间群为P2_(1)/c,晶胞参数为:a=5.11446(19)A,b=11.4930(4)A,c=9.4084(3)A,β=95.692(4)°,V=550.30(3)A3,Z=2;配合物(2)属于单斜晶系,空间群为P2_(1)/c,晶胞参数为:a=11.7198(4)A,b=8.5094(3)A,c=8.9703(3)A,β=111.765(4)°,V=830.82(5)A^(3),Z=4。对配合物(2)进行了磁性质研究,结果表明,铜离子之间存在反铁磁相互作用。
In this paper,two complexes,Fe(3 PCA)_(2)(H_(2)O)_(2)(1)and[Cu(3 PCA)(Im)]_(n)(2)(3 PCA=pyrazole-3-carboxylic acid,Im=imidazole),were synthesized by constant temperature water bath method and solvothermal method respectively.Their crystal structures were determined by X-ray single crystal diffractometer.The results show that the complex(1)belongs to the monoclinic system,the space group is P21/c,the unit cell parameters are:a=5.11446(19)A,b=11.4930(4)A,c=9.4084(3)A,β=95.692(4)°,V=550.30(3)A^(3),Z=2;the complex(2)belongs to monoclinic system with space group P21/c,the parameters are:a=11.7198(4)A,b=8.5094(3)A,c=8.9703(3)A,β=111.765(4)°,V=830.82(5)A^(3),Z=4.The magnetic properties of the complex(2)were studied.The results show that there is an antiferromagnetic interaction between copper ions.
